Hi all,

I've been working with PHP for the past month to develop a simple web-site.  It has two pages that are served dynamically - the events page and the members page.  These are public pages.  It has 3 other static pages.

I've created the database tables in MYSql.  The events page has one table.  And the teachers page has a few more - particularly - one primary table for member basics,  another for member address.  These are one to one with the primary driver being the member basic table since it will also include an active/inactive flag.  The 2 files that get used are member credentials, and member specialties.  These have one to many relationship with basics table.

So far I've been using PHPadmin to create dummy data.  But my next step is to create an admin page for the events - where the admin can maintain any event.  Then I need to create an admin page for the users.   (Further down the line each user will be able to maintain their own events and information.)

I was actually hoping to find a code generator to help with these.  I know it would be a great learning experience to do them on my own.  But I would also like to move a little faster than glacial speed.  I'm an RPG programmer by day.  So I have programming experience - just new to the web.

I've looked at MySQl Table Editor from phpguru.  But it used Pear - which I'm not using.  And it's not clear to me whether/how it will handle the one to many relationships.  I also looked at PhpMyEdit - but it looks like overkill and some of the documentation I've seen recommends that the first column in every table be unique(auto incremented) and I haven't done that with the children tables that have a one to many relationship.  And I'm not quite sure why I would do that.

Can anyone recommend a tool???

And/or a really good tutorial that includes multiple file being updated at the same time?

I'd rather not reinvent the wheel.  I apologize for the long first post.  I've tried to google - but I actually kind of overwhelmed by the amount of material I find on PHP.

Thanks.
Vic

Hello,

Here's the weird thing, some of the pages shows the results, and some pages just won't show results at all, and I'm not getting any errors

here is the one that doesn't

Code: [Select]
<?
function display_mptt($user) {
global $db;
// retrieve the left and right value of the $root node

$sql2 = "SELECT * from mptt where id='25'";

$result2 = mysql_query($sql2 ,$db);
if(!$row2 = mysql_fetch_array($result2)) echo mysql_error();
echo '<h1>Users List</h1>';

// start with an empty $right stack
$right = array();

// now, retrieve all descendants of the $root node
  $sql = "SELECT * from mptt WHERE 'left' BETWEEN '".$row2['left']."' AND '".$row2['right']."' ORDER BY 'left' ASC";
 $result = mysql_query($sql ,$db);

 // display each row
  while ($row = mysql_fetch_array($result)or die(mysql_error())) {
  // only check stack if there is one
  $count = mysql_num_rows($result);
  if (count($right)>0) {
  // check if we should remove a node from the stack
  while ($right[count($right)-1]<$row['right']) {
  array_pop($right);
  }
  }
 // display indented node title
 
 // add this node to the stack

 
  $var3 = '10';
    echo "<table width='589' border='1'>
<tr>
<th>ID</th>
<th>Name</th>
</tr>";
 
 echo  "<tr><td><a href=\"user.php?id=".$row['id']."\">".$row['id']."</a></td>";
echo "<td>" . $row['title'] ." </td>";

echo   "</tr>";
 
 echo "</table>";
  $right[] = $row['right'];
  }
 }
 
 

   display_mptt(1);     ?> 

and here is the page that does

Code: [Select]
<?
function display_mptt($user) {
global $db;
$id = $_GET['id'];
// retrieve the left and right value of the $root node
$sql2 = "SELECT * from mptt where id= ".$id."";

$result2 = mysql_query($sql2 ,$db);
if(!$row2 = mysql_fetch_array($result2)) echo mysql_error();
echo '<h1>Your Tree</h1>';

// start with an empty $right stack
$right = array();

// now, retrieve all descendants of the $root node
  $sql = "SELECT * from mptt WHERE `left` BETWEEN ".$row2['left']." AND ".$row2['right']." ORDER BY 'left' ASC";
 $result = mysql_query($sql ,$db);

 // display each row
  while ($row = mysql_fetch_array($result)) {
  // only check stack if there is one
  if (count($right)>0) {
  // check if we should remove a node from the stack
  while ($right[count($right)-1]<$row['right']) {
  array_pop($right);
  }
  }
 // display indented node title
  echo str_repeat('&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;',count($right)).$row['title']."<br>";
 // add this node to the stack
  $right[] = $row['right'];
  }
 }
 
  display_mptt(1);
  ?>

Hi Everyone,

I have an ecommerce store that I have done some coding for, and each category has some coding to create pages to display items in that category.  For some reason, I am getting a couple of "ghost" pages on the end of a couple categories.

For example, look at this page:  http://www.autismcommunitystore.com/view.php?category=4

Pages 5 & 6 are blank - page 4 has the last of the items in the category.  I have a table called prods_to_cats which connects the products and the categories (a many to many relationship).

I'm posting the code here - could someone just let me know if they spot something that looks like trouble?

Thank you in advance for your time!

Code: [Select]
<?
$category=$_REQUEST['category'];
$showcategory=$category;

include 'connect.php';

$thiscategory = mysql_query("SELECT * FROM category WHERE category_id=$showcategory", $dbh);
$thisrow = mysql_fetch_array($thiscategory);
$this_des=$thisrow["category_description"];
$this_text=$thisrow["category_text"];

$titlekey="Products listed in $this_des at Autism Community Store 877-422-5932";


// If current page number, use it
// if not, set one!

if(!isset($_GET['page'])){
    $page = 1;
} else {
    $page = $_GET['page'];
}

// Define the number of results per page
$max_results = 40;

// Figure out the limit for the query based
// on the current page number.
$from = (($page * $max_results) - $max_results);

echo  '<div id="product">';
$result = mysql_query("SELECT DISTINCT product.id, product.* FROM prods_to_cats INNER JOIN product ON prods_to_cats.id=product.id WHERE prods_to_cats.category_id=$showcategory ORDER BY product.title ASC LIMIT $from, $max_results", $dbh);

Hi everyone, 

I am a beginner web designer and a novice php user. I am a regular forum user and understand that you should always do a search and try to find the answer yourself but I have done that and didn't get any results (or I didn't understand them!).

So I ask for some assistance - either you can tell me the code or link me to the correct answer.

I am working on a website that I have built a enquiry form for and it has a php script for it. I have managed to get the form running properly and got the reCaptcha working correctly (with a custom error page) but I do not understand how to add custom error pages for incomplete email addresses, empty email addresses, or for a blank form? I tried using the same tactic I used for the reCaptcha error page but it didn't work - probably because I was guessing and just tried it in a bunch of different places.

The error msg that displays now is just a plain white page with the msg - Email address is invalid appearing at the top left.
While this is suitably functional it doesn't really look like much so I want to build a custom page for each error that could happen.

So the code is below - if anyone can point a beginner in the right direction I would be super happy.  :mrgreen:

if you need anymore code or other details just tell me and I will post them up.

The url of the form page is http://www.sunsolutionshomeimprovement.com/onlinesales.html

This is the code I think you will need - I got it from a demo php script that I have modified. As I said I don't have much clue what I'm doing so I just posted it exactly how it looks - if I over did it I apologize... :oops:

68.// Validate email field.
69.
70.if(isset($_REQUEST['email']) && !empty($_REQUEST['email']))
71.{
72.
73.if(preg_match("/(%0A|%0D|\n+|\r+|:)/i",$_REQUEST['email'])){$errors[] = "Email address may not contain a new line or
74.a colon";}
75.
76.$_REQUEST['email'] = trim($_REQUEST['email']);
77.
78.if(substr_count($_REQUEST['email'],"@") != 1 || stristr($_REQUEST['email']," ")){$errors[] = "Email address is invalid";}else{$exploded_email = explode("@",$_REQUEST['email']);if(empty($exploded_email[0]) || strlen($exploded_email[0]) > 64 || empty($exploded_email[1])){$errors[] = "Email address is invalid";}else{if(substr_count($exploded_email[1],".") == 0){$errors[] = "Email address is invalid";}else{$exploded_domain = explode(".",$exploded_email[1]);if(in_array("",$exploded_domain)){$errors[] = "Email address is invalid";}else{foreach($exploded_domain as $value){if(strlen($value) > 63 || !preg_match('/^[a-z0-9-]+$/i',$value)){$errors[] = "Email address is invalid"; break;}}}}}}
78.
79.)
80.
81.// Check referrer is from same site.
82.
83.if(!(isset($_SERVER['HTTP_REFERER']) && !empty($_SERVER['HTTP_REFERER']) && stristr($_SERVER['HTTP_REFERER'],$_SERVER['HTTP_HOST']))){$errors[] = "You must enable referrer logging to use the form";}
84.
85.// Check for a blank form.
86.
87.function recursive_array_check_blank($element_value)
88.(
89.
90.global $set;
91.
92.if(!is_array($element_value)){if(!empty($element_value)){$set = 1;}}
93.else
94.
95.
96.foreach($element_value as $value){if($set){break;} recursive_array_check_blank($value);}
97.
98.)
99.
100.)
101.
102.recursive_array_check_blank($_REQUEST);
103.
104.if(!$set){$errors[] = "You cannot send a blank form";}
105.
106.unset($set);
107.
108.// Display any errors and exit if errors exist.
109.
110.if(count($errors)){foreach($errors as $value){print "$value<br>";} exit;}
111.
112.if(!defined("PHP_EOL")){define("PHP_EOL", strtoupper(substr(PHP_OS,0,3) == "WIN") ? "\r\n" : "\n");}
113.
114.// Build message.

I don't think there is anymore that is relevant?

I just want to reiterate that I know nearly nothing about this stuff so if you could keep your answers simple it would help a lot - cheers!
